SHOE-TREE.

Specification of Letters Patent.

Application filed October 29, 1909.

I v Patented 0613.20, 1914;. SerialNo.525,360.

To all whom it may concern:

Be it known thatI, JOHN S. I'IANSEN,-I-t citizen of the United States,residing at Brockton, in the county of Plymouth and State ofMassachusetts, have invented certain Improvements in Shoe-Trees, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to certain improvements in shoe-trees or forms,lasts and similar devices. v i

One of the objects'of the invent c'njis to produce a shoe-tree or formin which the usual fore part and the heel part thereof are connected bymeans which permits "the easy insertion of the tree in a shoeso as tosnugly I fit the same, or to be quickly withdrawn therefrom, combinedwith an improved adjusting device, so arrangedandconstructed as toprovide for changing the length of the also to permit relativelongitudinal or sliding movements thereof, together with a very simple,convenient, and durable form of adjusting device which I have found tobe admirably adapted to the purpose of effecting the longitudinalmovements of the parts of the shoe-tree. Thisv device, in the embodiment of the invention selected for illustration herein, is composedof a. suitable rotatory member, such, for example, as a nut, which issupported by and turns freely on a part joincdto one of the connectingmembers and is in threaded engagement with a cooperating element,such,for example, the teeth of a rack formed on, or carried by, theother of said members. Preferably, such rotatory member is in swiveledengagement with a slide which is pivotally oined to the first-mentionedconnecting member; and 1 is constrained to movthe other connecting"member; j I

In the embodiment of the invention shown herein,the numeral 1 indicatesthe fore part, which may be constructed of wood, or any other 'suitablematerial, in, the rear portion of which is preferably formed a kerftorec eive the forward end of her 3, the same beingcshownas pivotallyconnected with the fore part by a suitable pin 2, though anyequivalent'means may be employed to .movably with each! other. Themember 3 isformed with a slot, &, and is also formed, or p ro-. vided,upon each of its opposite edges with a rack comprising a plurality ofteeth, 5, which areso'arranged as to cooperate with a worm or threadformed interiorly of a nut, 7, which surrounds and travels upon themember 3'in the same manner as upon an externalscrew-thread, the nuthavingpret erably an e'vternal roughened surface to enable itto be moreeasily turned through engagement with the operators thumb and fin] ger.The nut 7 is carried by a slide, '6, to which it is confined byshoulders, S, 8, on the slide, or by other suitable means which willpermit free turning movements of the nut relatively to the slide, butwill prevent any relative longitudinat movements of these parts. a I

The heel part, 14, which may be of rounded, ellipsoidal, or any othersuitable form, has secured thereto the member, 10,, which is providedwith an extension having an angu lar portion, 13, to constitute a handlefor the convenient insertionof the tree ma shoe or for its removaltherefrom, as well as for properly manipulatingthe toggle members, 3,and 10. At its forward end the member aconnecting memconnect said parts7 its a v 6 0 In the drawings, Figure illustrates,;in

i is pivotally connected with the slide 6 by a pin, ll, whichvalsopasses through-the slot 4.

By thisconstruction it willbe seen that the members 8- and 10 arepivotally joined:

together and that the member 3 is pivoted to the fore part so as to turnrelatively.

thereto, whereby, if the parts of the tree are in the position shown bydotted linesin the,

drawing and are inserted in a shoe, and downward pressure applied to theconnecting members through the handle, said memberswill act in themanner of a toggle to separate the fore and heel parts of the tree andto seat them firmly and snugly against the inside of corresponding partsof the shoe. If adjustments ofthe tree are desired, the operator mayapply his thumb and a finger to the nut 7, and by turning it in onedirection will cause the nut to travel alongthe teeth 5 rearwardly toseparate the parts of the tree and thereby increase its length, and byturning thenut in the opposite direction will cause it totravel alongthe teetli in the proper direction to contract said parts andtherebydecrease the length of the tree. These adjustmentsmay beaccomplished very easily, and with the hand which inserts the tree in,or removes it from a shoe, either prior to or after the tree has.

been inserted in position. In the latter case, the threaded connectionbetweenthe nut 7 and the member 3 is such as to'provide a powerfulleverage which enables the operator, through said parts, to exert thedesired amount of stretching pressure against the fore part and heelpart of theshoe.

It is to be understood that the invention is not limited to the detailsof construction herein shown and described, but suchdetails may bevaried and the invention may be embodied in other forms, withoutdeparting from the principles thereof.

Having thus described my invention,

whatI claim as new and desire to secure by Letters Patent of-the UnitedStates, is

1. Ashoe-tree having, in combination, a fore part, a heel part, a memberconnected with one of the said parts and provided with a rack, a memberconnected with the other of said parts, a slide pivoted to the lastnamedmember and a rotary device carried by said slide and constructed andarranged to engage the teeth of said rack, to effect longitudinaladjustments of the shoe-tree.

2. A shoe-tree comprising a iore part, a heel part, a toggle memberpivotally connected with one of said parts and having its edges providedwith teeth, a toggle member connected with the other of said parts, aslide pivoted to the last-named member and arranged for longitudinalmovements relatively'to the first-named member, and a nut encircling theslide and toothed memher and rotatively mounted on said slide whereby itis adapted to cooperate with said teeth in eflecting relativeadjustments of the fore and heel parts.

3. A shoe-tree comprising a tore part, a heel part, a togglememberconnected with one of said parts, said member having a slot andalso having its edges provided with teeth, a toggle member connectedwith the other of said parts, a slide, means passing through the slot inthe first-named toggle member and plvotally connecting said slide andlastnamedtoggle member, and a rotatory device carried by said slide andadapted to cooperate with said teeth in eflecting relative adjustmentsof the fore and heel parts.

In testimony whereof I have signed my name to this specification in thepresence of :two subscribmg witnesses.
